CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 315,602, dated April 14, 1885.

Application filed July 25, 1884. (No model.)

To all whom itmay concern.-

Be it known that I, J OHN A. CRAIG, of Lauderdale, in the county of Lauderdale and State of Mississippi, have invented a new and useful Improvement in Gar-Oouplings, of which the following'is a full, clear, and exact description, reference being had to the annexed drawings, forming part thereof.

This invention relates to improvements whereby ordinary pin-and-link couplings may be coupled automatically.

In the drawings, Figure 1 is a side elevation of part of a car. Fig. 2 is a vertical section of part of another car in position for coupling with the first, and Fig. 3 is a crosssection of the draw-head.

A indicates the draw-head, and Bis a pendent link-lifter formed by bending a rod about the draw-head and turning its ends 0 up through perforations C in the bottom of the draw-head. The weight of the lifter resting on top of the draw-head causes the ends 0 to lie below the chamber of the draw-head out of the way of the entering link; but when the link is coupled with the draw-head its outer end is to be lifted for coupling with another car by lifting the device B and causing its ends 0 to bear up against the link. For this purpose a rod, D, is connected to the lifter and extended to the topof the car, where it is held in a support, E. This support is-provided with a series of shoulders, F, of differ e nt elevations, arranged around the opening in\the support E in which the rod D works,

and the upper end of the rod, being bent to which the rod may be supported on any one of the shoulders F, according to the height of the coupler with which the link is to be coupled. The jarring of the cars in coupling will cause the rod D to drop and release the link. The pin H is supportedin a yoke, I, secured to the upper part of the draw-head, and alift" ing-rod, J, is attached to thepin near its middle, and supported in a perforation in the support E. The pin is supported in a raised positionby a spring-bumper, draw-head. When the pin is lilted,the bumper is pressed outward by its spring in position for forming a rest for the pin, and when the entering link presses the bumper back the falls and engages the link. The pin may pin be supported by a shoulder on the rod J K, arranged in the adapted to engage the support E, if preferred.

What I claim is- In a car-coupling, the combination,withthe draw-head A, of the link-lifter consisting of the bail-shaped rod B, with its side portions curved or extended at their lower ends forwardly and inwardly, saidlatterportionshaving upwardly-extended portions O,projecting up into the link passage or chamber, substantially as shown and described, and for the purpose set forth.
